I am trying to clone a huge repo using GIT SVN I am getting the following error using: git svn fetch

git svn fetch -q -r 64480
error: index uses e 2. extension, which we do not understand
fatal: index file corrupt
write-tree: command returned error: 128

I have the svn repo locally and serving using the svnserve command from local computer thus no issues with netowrking.

svnadmin verify reports no issues.
